95 caravan runs a few seconds after shut off

the pcm energizes that relay. should be a dark blue wire with a yellow stripe going from pcm pin 67 to pin 8 on power dist center. check all fuses then check wire. Is the check engine light on with key on? Possible bad pcm.

Some times the new part is bad. If you put the old one in do all the new symptoms go away if they do take the part back.

The 95 Caravan is great for giving you trouble codes. However they are two digit codes. There should be a blink sequence followed by a short pause then another blink sequence (example 2 blinks, short pause, 3 blinks... Then 5 blinks, pause, 5 blinks which means no more codes. Turn key from off to run three times and leave in run and watch check engine light to count blinks. Disconnecting negative terminal on battery for 30 seconds clears codes.

If you boot for a few seconds and shuts down and gives you bad key problem could be the immobilizer which has the function to recognize the key and connect the engine computer which can be resolved by reprogramming the key. Thanks

Oil pressure sensor blocked or faulty. both oil level sensor and oil pressure sensor activate the oil light. engine goes into safe mode and shuts off ignition.

too much fuel , injector or fuel pressure regulator ?
